I have a Sony VAIO Duo 11 (SVD112...) which features both multi-touch and stylus input. However, booting up Ubuntu 12.10 gives me

no stylus reaction

touch input works very strange: when I touch with 1-3 fingers, usually nothing happens but sometimes there is some reaction

when I tap the screen with 4 fingers, the dash shows up, consistently

Where can I start to find out the underlying issue and how to fix it?

EDIT: On Ubuntu 12.04.1 the touchscreen isn't recognized at all.

EDIT2: On Fedora 18, the touchscreen works a little bit better. I have found out that the USB ID of the touchscreen is not contained in the hid-ntrig module, so that's probably why some of the quirks needed for it are not appplied.

I have filled a bug report about touchscreen. It is at https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/1121379 . Please press the "affects me too" button in order to increase the "heat" and make more people/developers notice it. I can help with more tests or trying fixes. So if you have to propose something to test (e.g. install a newer kernel or X version, apply some patch, tryout some config), please tell me.
